The infection with H. Pylori stimulates a signaling cascade that causes the generation of Cytokines and provokes Oxidative stress that is involved in the chronic inflammatory response leads to Gastric cancers. Reactive oxygen species (ROS) produce 8-Hydroxydeoxyguanosine (8-OHdG), the persistent oxidative DNA damage product. The study objective was to assess if there was a link between inflammatory cytokine levels and the presence of Oxidative DNA damage in Gastric tumor patients. In addition, evaluation of the diagnostic and prognostic value of Oxidative DNA damage and inflammatory cytokine biomarkers for Stomach cancers is being conducted. The study was accomplished on medically diagnosed Stomach cancer patients before any form of treatment. A total of 33 patients with Gastric cancers were selected and divided into Stages I, II, and III according to clinical pathology, and 32 age-matched healthy subjects as a control group. The Serum 8-OHdG, IL-6, TNF-α, IFN-γ & CEA were evaluated. The results revealed a highly significant rise (P<0.0001) in blood levels of 8-OHdG, TNF-α, & IFN-γ, and a non-significant (P=0.4747) increasing in IL-6 in GC patients compared to Controls, with levels gradually increasing as disease stages progressed. Furthermore, in GC patients, there was an insignificant (P=0.3472) positive correlation (r=0.1292) among 8-OHdG, IL-6, and CEA levels, but a noteworthy (P<0.0001) positive correlation (r=0.7235) among 8-OHdG, TNF-α, and CEA levels. In GC patients, however, there was an insignificant (P=0.6342) negative correlation (r=-0.06559) among 8-OHdG, IFN-γ, and CEA levels. The results of the current study show a strong link between serum levels of the 8-OHdG as well as inflammatory cytokines in GC patients. The significant enhancement in oxidative DNA damage, as well as overexpression of inflammatory cytokine biomarkers and CEA in the blood suggests that Oxidative stress and chronic inflammation are included in GC carcinogenesis. These observations suggest that 8-OHdG, TNF-α, & IFN-γ are viable biomarkers for the Gastric tumor prediction.
Summary
The fundamental turning point in American policy towards the Iran was the success of the Islamic revolution in Iran 1979 . Since than U S policy has been hostile to Iran . After the events 11 September 2001 , there was an American idea of dialogue with some countries opposed to US policy , including Iran . In 2004 the United States launched the Greater Middle East project , which contain a range of political , economic and cultural proposals for the region , all of which were in the interest of the United States and ( Israel ) , which Iran opposed . The failure of U S projects in region prompted the United States to agree with Iran on the nuclear file . On 8 May 2018 U S President Donald Trump of

Background: We aimed to investigate the accuracy of salivary matrix metalloproteinases (MMP)-8 and -9, and tissue inhibitor of metalloproteinase (TIMP)-1 in diagnosing periodontitis and in distinguishing periodontitis stages (S)1 to S3. Methods: This study was a case–control study that included patients with periodontitis S1 to S3 and subjects with healthy periodontia (controls). Saliva was collected, and then, clinical parameters were recorded, including plaque index, bleeding on probing, probing pocket depth, and clinical attachment level. Diagnosis was confirmed by assessing the alveolar bone level using radiography. Salivary biomarkers were assayed using an enzyme-linked immunosorbent assay. Results: A total of 45 patients (15
... Show MoreAcute Respiratory Distress Syndrome (ARDS) causes up to 40% mortality in humans and is difficult to treat. ARDS is also one of the major triggers of mortality associated with coronavirus-induced disease (COVID-19). We used a mouse model of ARDS induced by Staphylococcal enterotoxin B (SEB), which triggers 100% mortality, to investigate the mechanisms through which Δ9-tetrahydrocannabinol (THC) attenuates ARDS. SEB was used to trigger ARDS in C3H mice. These mice were treated with THC and analyzed for survival, ARDS, cytokine storm, and metabolome. Additionally, cells isolated from the lungs were used to perform single-cell RNA sequencing and transcriptome analysis. A database analysis of human COVID-19 patients was also performed t
... Show MoreBiomarkers to detect Alzheimer’s disease (AD) would enable patients to gain access to appropriate services and may facilitate the development of new therapies. Given the large numbers of people affected by AD, there is a need for a low-cost, easy to use method to detect AD patients. Potentially, the electroencephalogram (EEG) can play a valuable role in this, but at present no single EEG biomarker is robust enough for use in practice. This study aims to provide a methodological framework for the development of robust EEG biomarkers to detect AD with a clinically acceptable performance by exploiting the combined strengths of key biomarkers. A large number of existing and novel EEG biomarkers associated with slowing of EEG, reductio

No single etiologic factor fully accounts for the spectrum of abnormalities in the polycystic ovary syndrome. Different changes in hormonal, metabolism and the inflammatory markers as squealy of PCOS with adverse effect on the women life. OBJECTIVE: To study the relationship between polycystic ovary syndrome and levels of C-reactive protein, human interleukin and hormonal and metabolic alteration in women with PCOS PATIENTS AND METHODS: Thirty women with Polycystic Ovary syndrome (PCOS) and other thirty women without PCOS were included. Venous blood samples were taken in early follicular phase of menstrual cycle [day
... Show MoreThe current study deals with the performance of constructed wetland (CW) incorporating a microbial fuel cell (MFC) for wastewater treatment and electricity generation. The whole unit is referred to as CW-MFC. This technique involves two treatments; the first is an aerobic treatment which occurs in the upper layer of the system (cathode section) and the second is anaerobic biological treatment in the lower layer of the system (anode section). Two types of electrode material were tested; stainless steel and graphite. Three configurations for electrodes arrangement CW-MFC were used. In the first unit of CW-MFC, the anode was graphite plate (GPa) and cathode was also graphite plate (GPc), in the second CW-MFC unit, the anode was stainless st
